Merge branch 'iu-boot/master' into 'u-boot-arm/master'
Conflicts: arch/arm/cpu/arm926ejs/mxs/Makefile board/compulab/cm_t35/Makefile board/corscience/tricorder/Makefile board/ppcag/bg0900/Makefile drivers/bootcount/Makefile include/configs/omap4_common.h include/configs/pdnb3.h Makefile conflicts are due to additions/removals of object files on the ARM branch vs KBuild introduction on the main branch. Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
